Occupational Safety: Portable Exposure Assessment System for Prevention of Musculoskeletal Injury

CDC researchers have developed the Portable Exposure Assessment System (PEAS), a field-based, remotely deployed tool to monitor and provide early warning of working conditions that have a high likelihood of musculoskeletal injury. PEAS is a noninvasive, real-time, instrument-based system. Sensor technology simultaneously measures and collects data regarding the body loads and awkward postures imposed by package handling as well as driving-related, low-frequency vibrations.

Swing-Away Winch Cathead Guard

Shrimp boat operators use two trawl retrieval mechanisms mounted on the same winch frame. The main spools are used in the first operation; the shrimpers stand within inches of rotating cathead drums and guide incoming wire rope onto the main spools. Second, lazy lines are wrapped multiple times around each of the two spinning catheads (horizontal beams that raise and secure the anchor). Lastly, the guarding ends are pulled by the operators to cinch the rope to the rotating spool aiding trawl retrieval, but poses a hazard for operators to get entangled in the spinning cathead spools.

Near Real-time, Low-cost, Hand-held Sensors for Measuring Elemental Concentration of Airborne Particles for Indoor or Outdoor Air Quality Monitoring

Airborne particles can have great impact on air quality, weather, and human health. In particular, long-term inhalation of toxic particulate matter in workplaces could pose a significant health risk. NIOSH scientists have developed a new, low-cost approach based on application of atmospheric radio frequency glow discharge (rf-GD) optical emission spectroscopy for near real-time measurement of elemental concentration in aerosols. The method involves collection of aerosol particles on an electrode tip in a coaxial microelectrode system, followed by excitation of the particles using rf-GD.

A Method to Isolate Tumor Specific T-Cells or T-Cell Receptors from Peripheral Blood using In-vitro Stimulation of Memory T-Cells

Adoptive cell transfer (ACT) and T-cell receptor (TCR) therapies use lymphocytes that target somatic mutations expressed by tumors cells to treat cancer patients. One of the challenges of these therapies is the identification and isolation of mutation-specific cells and TCRs. While neoantigen specific cells are relatively abundant in the tumor, they are far less common in peripheral blood, a more accessible source of T cells. 

Chimeric Antigen Receptor (CAR) that Targets Chemokine Receptor CCR4 and its Use in Treating Cancer

The chemokine receptor, CCR4 is a seven transmembrane G protein-coupled cell surface receptor molecule with selective expression on cells of the hematopoietic system. In adult T cell leukemia (ATL), the cell-surface expression of CCR4 on leukemic cells has been found to be nearly universal. Therefore, a CCR4-directed chimeric antigen receptor (CAR) -cell may provide an effective therapeutic against ATL.

Highly Soluble Pyrimido-Dione-Quinoline Compounds: Small Molecules that Stabilize and Activate p53 in Transformed Cells

The tumor-suppressor p53 protein plays a major role in tumor development. Most human cancers fail to normally activate wild-type p53, which is at least partly responsible for the unregulated growth of cancer cells and their failure to undergo apoptosis. While many chemotherapeutics enhance p53 levels, their non-specific DNA damage (genotoxicity) causes unfavorable side effects.
 

Single domain CD4, HIV-1 Antibodies, and Fusion Proteins for treatment of HIV

Soluble forms of human CD4 (sCD4) inhibit HIV-1 entry into immune cells.  Different forms of sCD4 and their fusion proteins have been extensively studied in animal models and clinical trials as promising HIV-1 inhibitors. However, they have not been successful in clinical trials due to their transient efficacy.  sCD4 is also known to interact with class II major histocompatibility complex (MHCII) and, at low concentrations, could enhance HIV-1 infectivity. 

Nucleic Acid Nanoparticles (NANP) and Methods of Using Same for Controlled Immunomodulation

The technology is directed to compositions and methods of designing nucleic acid nanoparticles (NANPs) composed entirely of DNA, RNA, or DNA and RNA to achieve desirable immunostimulation and decrease undesirable effects on the immune system by changing the composition of the NANP. Benefits of the invention include the desirable activation of the immune system by these particles to increase the efficacy of vaccines and immunotherapies.
